- Title
- Trout and Salmon Inland Stream Regulation Types (Layer 2 of 3) - BTRA Polygons [Michigan]
- Description
- Features from the 1:24,000 scale National Hydrography Dataset (NHD) were used to depict inland stream trout and salmon type regulations. NHD features were altered to fit the extent of the regulations described in FO 200 and FO 210. Except for streams in the Michigan-Wisconsin Boundary Waters, any other inland stream not classified by type (1-4; GR, RA, BTRA) are still subject to trout and salmon fishing regulations as described on page 40 of the Michigan Fishing Guide. Please see pp. 24-25 for Michigan-Wisconsin Boundary Waters regulations. Note that the two inland stream trout and salmon regulation GIS layers only show the streams classified by type; these layers do not include any streams that are not classified by type. The regulation type associated with a stream feature is indicated in the RegulationType field and the designation status is indicated in the Designated field (with 0 as non-designated and 1 as designated). The RegulationType and Designated field are concatenated in the RegTypeDes to show the full type regulation and designation status. In some cases, a stream will have more than one regulation type assigned. In which case, the RegulationType field will have both types listed, as will the RegTypeDes field. Each regulation type is associated with specific rules for the length of the fishing and possession seasons, minimum size limits, and daily possession limits. See FO 200 and the Michigan Fishing Guide for more details about the individual regulation types. Regulation types are as follows: Type 1 - Type 1 Trout Stream; Type 2 - Type 2 Trout Stream; Type 3 - Type 3 Trout Stream; Type 4 - Type 4 Trout Stream; BTRA - Brook Trout Restoration Area; RA - Research Area Trout Stream; GR - Gear Restricted Stream. Designation status is either designated or non-designated. Designated trout streams are inland streams containing a significant population of trout or salmon, as identified by the State of Michigan. Designated trout streams are protected from certain activities, see the Michigan Fishing Guide or FO 210 for more details. All Type 1, Type 2, GR, RA, and BTRA are designated trout streams. Most Type 3 and Type 4 streams are designated trout streams. The main layer shows the majority of inland streams that are classified by type for trout and salmon regulations. However, there are some polygon features that cannot be displayed in this line layer and are therefore represented in the BTRA polygon layer. To show all inland streams that are classified by type for trout and salmon regulations, both layers must be displayed in the proper order using established symbology. The BTRA polygon layer should be displayed on the top of the main stream regulations layer. When displaying the inland trout and salmon streams with inland trout and salmon lakes Types A-F & Special Type, both of the stream layers should be displayed underneath the Types A-F & Special Type layer. For the main regulation type layer, set the drawing order so that specific regulations type display on top of others. Do this by opening the feature class properties in the Table of Contents in ArcMap, then go to Symbology, then Advanced, then Symbol levels and using the following order, from top to bottom: Type 4 Non Designated, Type 3 Non Designated, GR Type 4 Designated, GR Type 2 Designated, GR Type 1 Designated, GR Designated, RA Designated, Type 4 Designated, Type 4 BTRA Designated, Type 3 Designated, Type 3 BRTA Designated, Type 2 Designated, Type 1 Designated, and Type 1 BTRA Designated.
